Member Function Documentation

void SoGLUpdateAreaElement::initClass ( void  ) [static]

This static method initializes static data for the SoGLUpdateAreaElement class.

Reimplemented from SoElement.

SoElement * SoGLUpdateAreaElement::copyMatchInfo ( void  ) const [virtual]

This function creates a copy of the element that contains enough information to enable the matches() function to work.

Used to help with scenegraph traversal caching operations.

Implements SoElement.

void SoGLUpdateAreaElement::set ( SoState *const  state,
const SbVec2f origin,
const SbVec2f size 
) [static]

Sets the update area. This can, for instance, be used when rendering in the front buffer, to only render parts of the scene during a window expose event. origin and size is in normalized window coordinates.

SbBool SoGLUpdateAreaElement::get ( SoState *const  state,
SbVec2f origin,
SbVec2f size 
) [static]

Returns the current update area.

See also:
set()
SbVec2f SoGLUpdateAreaElement::getDefaultOrigin ( void  ) [static]

Returns the default update area origin, (0,0).

SbVec2f SoGLUpdateAreaElement::getDefaultSize ( void  ) [static]

Returns the default update area size, (1,1).
